Help Moving Past Guilt/Shame

Looking for guidance revolving around moving past things I regret. A little backstory, I’ve always had undiagnosed OCD. Constant ritual, saying things in my head over and over, having to be perfect with prayers. Things like that. I’ve been with my now wife for about 10 years. She’s perfect and such a great person. I’ve struggled with porn addiction for a while. In the beginning and more towards the 8 year mark in our relationship. Long story short, I did a lot of things I was ashamed of and regret. I was talking to people online about sexual desires, sending pictures, things like that. Talked with men and women, but mostly men. She found out, we worked through it, got married and have been great since. Flash forward, we’ve began studying the bible and I’ve felt deep guilt for my past. It would consume me and I’d confess things she already knew and some she may not have. Regardless, she’s forgiven me and has been great through this. I just hate that my brain feels the need to make me feel guilty by finding a ‘new detail’ or specific instance that I haven’t thought about since it happened. I feel the need to then confess even though she said she’s forgiven me and doesn’t want details. I just feel like I’m in an endless loop where I tell myself she doesn’t mean it, I’m a terrible person and don’t deserve her. She’s the love of my life we’re soulmates and I know she means what she says when she says she forgives me, but I just and cannot move past the things I’ve done. I recently read about real event OCD and feel like that’s me. I also feel like I keep convincing myself I’ve done worse things and I’m lying to her when I’ve already confessed everything plus she said she’s doesn’t want details. Just looking for help to move past these constant thoughts of people I talked to or interactions I did. I don’t want to think about those. I just want to think about my wife and the good things we have. Also can’t shake the deep burning guilt I feel in my stomach. Any help is greatly appreciated. Thank you. I just want it to get better and move on for me and my wife’s sake. Thanks again.
